Soon after he is tasked by locals with re-activating "jammed" local Cell Towers, and regularly uses his cellphone throughout the game, but he nor any of his rescued friends/ friendly locals ever even consider trying to contact anyone in their native California, nearby embassies or the U.S. authorities which would definitely respond in aid or rescue very quickly.
